We all know that mobile versions of web sites should be minimalistic, efficient, action driven; in many cases a lighter version of a standard website.
But sometimes, users may want to access the standard site from their mobile devices if they are looking for specific information or if they are familiar with the standard website. This is more common with the proliferation of better mobile devices and more efficient, inexpensive data services.
What many mobile versions are failing to do is to provide a link to visit the standard site causing great frustration to the user.
What to do:
Give your mobile visitors the option of visiting the standard site, even if it’s just through a link in the footer. And from your standard site, you could give them the option to come back to the mobile site, making this link available on detected mobile devices.
